CoreWeave’s Mounting Credit Risk

We exited CoreWeave stock in July 2026 as the company’s finances were suddenly getting weaker. The stock is down more than 61% since our exit.  Some of our readers are asking if it might be time to jump back into the stock at current levels.  Our answer… hell, no!  

CoreWeave faces growing credit risk as elevated borrowing costs, substantial capital expenditures and a heavy debt burden put pressure on its financial flexibility.  With existing debt reportedly carrying interest rates around 8.3% and new financing potentially costing approximately 12-15%, the artificial intelligence infrastructure provider faces a widening gap between its financing costs and the cash flow needed to sustain its expansion.

The difference is financially significant. For every $1 billion of debt refinanced at 15% rather than 8.3%, annual interest expense would increase by approximately $67 million.  If billions of dollars must be refinanced at these higher rates, the additional interest burden could materially weaken the company's ability to fund operations, invest in infrastructure and meet future debt obligations.

Market-based indicators suggest investors are increasingly concerned.  Reports dated October 15, 2026, placed CoreWeave's five-year credit default swap (CDS) spreads above 1,100 basis points, alongside distressed bond yields of approximately 15% to 16%.  Reported CDS-implied default probabilities were around 63% to 64% over five years.  Although these figures are model-dependent rather than definitive forecasts, they indicate that credit markets are assigning a substantial premium to the risk of a credit event.  That, in and of itself precludes further investment in CoreWEave.

CoreWeave's financial position, however, is not defined by debt alone.  Its June 30, 2026, quarterly filing reported $5.524 billion in cash and cash equivalents and $10.014 billion available under existing credit facilities.  These resources provide a liquidity buffer, although credit-facility availability may be subject to conditions and should not be treated as equivalent to unrestricted cash.

The challenge is the company's considerable investment requirement.  During the first half of 2026, CoreWeave generated $3.663 billion in operating cash flow while spending $14.874 billion on investing activities.  Net interest expense also rose to $640 million in the second quarter, compared with $267 million a year earlier.  The gap between operating cash generation and investment spending increases the importance of continued access to external financing.

Nevertheless, elevated CDS spreads do not necessarily mean an imminent missed payment.  Long-term customer contracts, continued demand for AI computing capacity, project-level financing and access to lenders could help CoreWeave service its obligations.  The central risk is whether those resources remain sufficient if refinancing costs stay elevated or capital markets become less accessible.

For investors, the distinction between liquidity stress and actual default is crucial.  A restructuring, distressed refinancing or covenant problem could emerge before the company misses a scheduled payment.  Conversely, successful refinancing and stronger cash generation could reduce default risk.

Ultimately, CoreWeave's credit outlook depends on its ability to convert AI infrastructure demand into sustainable cash flow while managing debt maturities and financing costs.  Its elevated CDS spreads signal serious concern, but they should be interpreted as market-implied risk estimates—not certainty that default will occur.

Our preliminary estimate is that financing at 10–12% could be feasible for some debt tranches under favorable conditions, while 13–16% or more could be required for riskier unsecured borrowing in a stressed credit market. If credit conditions deteriorate further, refinancing may become difficult at any commercially sustainable rate.

The critical question isn't just the coupon. It's whether CoreWeave can raise enough capital, over the right maturities, without using so much cash for interest that it compromises its ability to grow and service existing obligations.

What current market evidence suggests

Recent reporting adds an important qualification: the 15–16% bond yield is not necessarily the rate CoreWeave would pay on every new loan.

• Reuters reported on October 20 that CoreWeave had roughly $50 billion of debt, including $24 billion in committed loans. Only 17% of its debt was due in 2027, with 42% due beyond 2030, according to JPMorgan's analysis.
• Goldman Sachs reportedly argued that current bond yields may overstate CoreWeave's actual cost of new financing because the company has been unable to issue new unsecured bonds for months. Project financing could offer another route.
• CoreWeave reportedly secured a $2.6 billion delayed-draw loan in August at SOFR(Secured Overnight Financing Rate) plus 5.5%, illustrating that secured, project-related borrowing can price differently from unsecured bonds.

Our estimated financing scenarios

These are analytical estimates, not quoted offers or guaranteed borrowing rates.

What that means over five years

Our central estimate is that CoreWeave would need to secure a blended financing cost of approximately 10–12% on substantial new borrowing to avoid making its interest burden even more punitive. That is a target scenario, not a prediction that lenders will offer those terms.

The bigger issue is whether CoreWeave can finance its infrastructure through secured project loans and customer-backed contracts rather than relying heavily on unsecured corporate debt. That distinction could determine whether it continues investing at scale or faces a refinancing squeeze.

And we’re NOT convinced CoreWeave can pull this off.  We’re out!
